Document Type and Number:
WIPO Patent Application WO/2023/027204
Kind Code:
A1
Abstract:
The present invention relates to a phosphor wheel device and an image projection device comprising same. A phosphor wheel device according to an embodiment of the present invention comprises: a base extending in a first direction; a plate which includes a protruded member attached to both ends of the base and extended in a second direction that intersects the first direction, and which rotates around a rotation axis; a phosphor layer which is disposed in one area of the base, and which reflects light incident on the base so as to output light of at least one color; and a blade which is disposed to be spaced apart from the plate in the second direction and which rotates around the rotation axis. Therefore, heat dissipation performance is improved and high luminance light can be output.
